Western blotting allows scientists to identify specific proteins in complex biological samples and determine relative abundance of a protein target. Rebecca Roberts is a science writer and ...

The high relative abundance of these tellurium isotopes gives tellurium the greater relative atomic mass. The atomic number of tellurium is 52 and the atomic number of iodine is 53, so these ...

If on the other hand, high local densities inevitably lead ... A unified theory of biogeography and relative species abundance and its application to tropical rain forests and coral reefs.
